My invention relates to combination cultivators, weeders, andfpulverizers and Vcertain objects ofthe invention are to provide a machine that willeflectively break up the soil,

5 lift the weeds and free them from dirt, 'pulverize the soil and pack it smoothly in place. Further objects are to provide means for raising and lowering the forward end of the machine, means forraising and lowering l the weeder, pulverizer and v packer drums, vmeans for raising and loweringthe cultivator discs, and means for tilting said Vdises forward and' backward. 3

'With the above and other objects in view l which will appear as the description'proceeds, the invention consists o f the novel construction, adaptation, combination and arrangement of parts hereinaftery described and claimed.

Referring to the drawings throughout which like reference numerals designate like arts, the frame of the machine comprises orward and rear beams 5 and 6 respectively that are held in'spaced relation by spaced side end beams 7 andS, 9 and 10 and by spaced central beams 11 and 12. The central beams extend forward of the beam 5, as at 13, where they are properly strengthened by braces and spreaders, and a clevis er other means such as shown at 14 is prov g the forward end These objects Vareaccom.

vided at the forward end of said beamsv whereby lthe device may bedrawn lover `the ground as will be understood;

lThe weight ef themachine is mainlyl supported by a pair ofV ,tractor wheels designated by the numerals 15` and 16 that are mounted on shafts 17 and 18 which are iournaled lin bearings secured to, the beams 7, 8, 9,10, 11 and 12. `v Sprockets, 19 and 20 are liXed to ksaid shafts or tractor wheels and chains 21 and 22y extend therefrom to idler sprockets 23l mounted on the rear end corners ofthe machine ,frame as" shown in Fig. 2H. Said chains engage'the upper `teeth ofy sprockets 24 that' are fixed to yrelatively large drums 25 and` 26 and'double spring rollerdevices such as shown` at 2*( retain said chainsvin engagement with said sprockets; rlrhe drums 25y and 26 .revolve freely and independently onshafts 28 `and 29 and will obviously be caused -torotate in vdirections that are opposite tothe 'rotations of the wheels 1 5 and 16. Said drums are provided with relatively long sharp spikes 30'that are adaptedrto pick up weeds, shake the dirt from their roots and deposit themI on the surface of the ground where'theyV will be dried out by the sun. Said drums and spikes are also adapted `to pulverizeV and pack the soil whichhas been previously broken up by the'cultivater discs as hereinafter set forth. 'l

The drum shafts 28 and 29 are supported in box bearings 31 at either end whichV aremounted in frames 32. Springs 33 normally retain said bearings in the downward position and at kthe same time permit movement of the drums 25 and 26 when they encounter such obstacles as rocks or uneven ground. The frames' 32 are slidably mounted in guide frames 34 and a chain 35 is secured to ther tops of said @frames 32 which passes overa guide pulley 36and is secured to a hand lever 37 wherebyv the drums may beraised free of the ground as will be understood. TheU forwardend ofthe machineis supported by vcastors 38` and`39. Referring to Fig. 4 saidfcastors are prvidedr with bearthe ends of their spindles 42 whereby they may turn freely and independently. Said spindles are threaded and are slidably mounted in bearings 43 fixed to the forward beam end portions 13. Said spindles threadedly pass through worm gears 44 mounted in said bearings and which are engaged by the worm end of a rod 45 having a wheel 46 fixed to its remote end. By

turning said wheel it will be'obvious that the forward end of the machine may be raised or lowered as desired.

Referring particularly to Fig. 5, the cultivator discs 47 have scalloped cutting edges p and are mounted on the downturned finger end portions 48 of arms 49. By means of sleeves 50 riveted to said discs and which serve as bearings for said finger portions said discs revolve freely and are retained in place by nuts 51 on their lower ends and by nuts 52 `adjacent the upper ends of said sleeves with an outside nut 53 threaded over the ends of said sleeves to exclude dust and other foreign matter.

The arms 49 are connected through universal joints 54 to eccentric rods 55 and 56 journaled to thev frames of the machine. Chains 57 extend from said arms over grooved cams 58 to hand levers 59. It will thus be obvious that by shifting said levers forward or backward the arms 49 with their discs 47 will be lowered or raised. 'Y Y For the purpose of tilting the discs 47 forward to makethem cut into the ground or backward to free them from' cutting into the ground a lever 60 is used for the eccentric rod and a corresponding lever 61 for the eccentric rod` 56. The extended portions 62 of the universal joints 54 are keyed to said eccentric rods and links 63 connect said eccentric rods with the ends of the levers and 6l which are pivoted at 64. By shifting said levers it will be apparent that said eccentric rods will be pivotally raised or lowered as indicated in full'and dotted lines in Figs. 2 and 3 of the drawings. By lowering said rods the discs will, by means of the arms 49, be tilted forward and by raising said rods the discs will be tilted backward as will be understood. Spacer springs'65 are interposed between the arms 49 for the purpose of retaining said arms normally in their proper spaced relation.

It will now be apparent that I have provided a machine that will breakup the soil, free it from weeds, pulverize and pack the broken soil, and which embodies control and adjustment means for each of its functional elements. I-Iaving thus described my invention, it being understood that minor changes may be resorted to in its construction without departing fromits scope and spirit, what I claim anddesire to secure by Letters Patent of the United States is:

posite halves of the frame, means for raising and lowering said discs, and means for tilting said discs forward and backward.

2. A combination cultivator weeder and l pulverizer comprising a frame, a pair of tractor' wheels, two relatively large spiked drums mounted for independent rota-tion at the rear of the frame, a chain drive arranged to rotate said drums in directions contrary to the directions of rotation of the tractor wheels, spring .frame box bearings for the drums, means for raising and lowering said drums, two sets of cultivator discs mounted on substantially vertical axes in opposite halves of the frame, means for raising and lowering said discs, and means for tiltingsaid discs forwards and backwards.' f

In testimony whereof I aix my signature.
